Slave trade from Americas

Since Thor Heyerdahl asserted that Polynesia was first colonized from the Americas (Heyerdahl 1950), geneticists have sought—but have not found—any evidence to support his theories. (12644966)

Native American Y chromosomes are detected on the Polynesian island of Rapa. However, this, together with other odd features of the island’s Y-chromosomal gene pool, is best explained as the genetic impact of a 19th century Peruvian slave trade in Polynesia. (12644966)
